Buoyant Behavior
Combine science and literature with this lesson on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an egg...

Activity # 13 Float or Sink?
Learners have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Note Taking And Skills And Lab Reports
Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...
Curated OER
Sink or Float?
Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...
Curated OER
Sink or Float
First graders explore items that sink or float. They cut and glue pictures of objects that they predict will sink or float. Students place thir pictures on a picture of a bucket of water. Students then color the objects that they had...
Curated OER
Will it SINK or Float?
Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.

The Floating Golf Ball
Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...
Curated OER
Move that Tower
Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Sink or Float: Exploring the Laws of Buoyancy
Young scholars explore the relationship between density and buoyancy. After watching a video explaining buoyancy, students discuss displacement and floating. Young scholars have a raft building competition. Afterward, they conduct...

Leaky Seal
Junior high schoolers explore possible theories for the cause of the Hunley submarine sinking. Through hands on activities, they investigate how to create a waterproof seal. Afterwards, they discuss how seals work and various...

Changing the Density of an Object - Adding Material
In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Changing the Density of an Object - Changing Shape
Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design an object out...

Changing the Density of a Liquid - Adding Salt
Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Ocean and Great Lakes Literacy: Principle 1
Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Density Studies of the Earth
Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

Buoyancy: What will float and what will sink
Students write and explain why an object sinks or floats. In this buoyancy lesson plan students demonstrate how items float or sink and graph the results.

Grand Designs And Great Failures
Young scholars extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or...

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
Exploring Buoyancy
Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

Physics of Boats
Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat on a...
Curated OER
Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.
